(Indianapolis, Ind.) – Texas Senator Ted Cruz trails Republican presidential frontrunner Donald Trump by 431 delegates, and 57 more are on the line in Tuesday’s primary election in Indiana.

Even without a mathematical chance to secure the Republican presidential nomination, Ted Cruz says he is competing the “entire distance”.

The Texas Senator told ABC’s This Week that no matter the outcome of Tuesday’s presidential primary in Indiana, his campaign will compete right through the GOP national convention in Cleveland.

During a weekend campaign appearance in Lafayette, Cruz bashed Trump for earning the support of former boxing champion Mike Tyson.

“And this is a choice for the people of Indiana. Do we stand with Carly Fiorina and Governor Mike Pence? Or do we stand instead with a convicted rapist, Mike Tyson?” Cruz asked his supporters.

Cruz picked up the endorsement of Indiana Governor Pence on Friday. Donald Trump reacted to that endorsement on Fox News Sunday, saying Pence’s compliments of Trump sounded more like he backed the GOP frontrunner instead.

“Most people think it was more of an endorsement for me than it was for Cruz. It was the weakest endorsement anyone has seen,” Trump said.

In the same poll, former Secretary of State Hillary Clinton has a narrow lead over Vermont Senator Bernie Sanders, 50 to 46 percent. Clinton appeared in Indianapolis Sunday. Sanders held a rally in South Bend Sunday and will appear in Evansville, Fort Wayne, and Indianapolis on Monday.

Monday at noon is the deadline for Hoosier voters to cast their ballots early at their county courthouse or other designated location.

Republican and Democrat voters head to the polls in Indiana on Primary Election Day. Polling places will be open Tuesday from 6:00 a.m. until 6:00 p.m. local time.
